I own it but I never bothered to re-install it when I upgraded the computer last year.
Most of my projects start to mix themselves as I am writing. If I were recording a band, and the project was somewhat more linear, maybe. But as it is, I always have elements of sound design active in the projets, busses, effects, even rudimentary EQ. I'll often have tons of tracks with just bits of audio, all split and routed to different places.
Just figuring out what needs to be exported how would be a waste of time.
That's not mentioning that I prefer and am much more comfortable with the automation in my DAW. At one point I toyed with the idea of routing out the audio from Logic to MixBus, but I'd rather focus on the mix than on technical stuff.
